Breeds in well-drained, hummocky arctic and alpine tundra with rocky ridges or outcrops and mixed vegetation (Dryas-lichen ridges, solifluction zones, sedge meadows, Salix or Betula communities, muskeg), vegetation sparse in most arid regions and highest slopes; denser and shrubbier vegetation at lower latitudes/elevations. Nests in dry, rocky areas (Holder and Montgomerie 1993). Winter in breeding habitat on in shrubby areas at or above treeline, in boreal forest on margins of lakes and rivers near treeline, and large shrubby openings near timberline (Weeden 1964).
